FRONTERA RESOURCES RELEASES OPERATIONS UPDATE

Frontera Resources Corporation (London Stock Exchange, AIM Market - Symbol: FRR), an independent oil and gas exploration and production company ("Frontera" or the "Company"), today released an operations update regarding its Mtsare Khevi Gas Complex.

Frontera is pleased to announce that it has received approval to proceed with the installation of the eight kilometer pipeline and related facilities within the Mtsare Khevi Field from the Georgian government. As previously announced, equipment required for the gas pipeline has been procured, mobilized, and stacked in the field and in key staging areas. First gas production is now expected within 120 days. The infrastructure will accommodate production from currently shut-in wells, and the Company is targeting production of approximately two million cubic feet per day of gas (57,000 cubic meters per day).

The Mtstare Khevi Field is situated within a larger play area of approximately 80 square kilometres referred to as the Mtsare Khevi Gas Complex and encompasses gas targets found between 300 metres and 5,000 metres in depth. Based on Frontera's internal estimates, analysis has revealed significant gas potential throughout this area of up to approximately 1.2 tcf of gas in place (28 billion cubic meters) and up to approximately 700 bcf of recoverable gas (19.8 billion cubic meters). An integrated geologic study, including data from a number of existing wells within the area such as the V-#18 well, previously referenced in the Company's 31 January 2012 announcement, is currently in progress to better understand and define the extent of this potential throughout the greater Mtsare Khevi Gas Complex.
